Technical Field

[0001] The utility model relates to the technical field of rail profile grinding equipment, in particular to a multi-degree-of-freedom angle-adjustable rail profile grinding trolley. Background Technique

[0002] Rail grinding is an important part of track repair work and an effective means for preventing and treating rail diseases. Through grinding, the wheel-rail contact relationship can be improved, the generation of rail diseases such as contact fatigue, wear, and corrugation wear (referred to as corrugation) can be prevented and delayed, the rail surface diseases can be repaired or reduced, the risk of rail fracture can be lowered, and the service life and maintenance cycle of track equipment can be extended.

[0003] Through grinding, rail surface diseases such as rail fatigue cracks, spalling, corrugation, abrasion, indentation, flash, uneven wear, and poor light band can be effectively solved.

[0004] Existing grinding instruments can only be used for grinding operations on a certain part of the rail. Due to the lack of a single function, it is not easy to meet various actual grinding conditions, reducing the efficiency of rail maintenance. In view of this, we provide a multi-degree-of-freedom angle-adjustable rail profile grinding trolley. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the utility model provides a multi-degree-of-freedom angle-adjustable rail profile grinding trolley, which solves the technical problem that it is not easy to quickly grind and maintain various parts of the rail in the existing technology, and achieves the ability to meet various actual grinding conditions by adjusting the angle in actual grinding operations, improving the efficiency of rail maintenance.

[0006] To solve the above technical problems, the utility model provides the following technical solution: A multi-degree-of-freedom angle-adjustable rail profile grinding trolley includes a box body slidably connected to a traveling and rail clamping device and a storage battery installed inside the box body. The storage batteries are distributed inside the box body, effectively reducing the entry of dust, debris, etc. generated during the rail surface profile grinding work of the overall device into the pan-tilt rotation device, thereby greatly improving the service life of the grinding device. A pan-tilt rotation device for adjusting the grinding angle and a lateral rotation mechanism are provided on the box body. A four-link lifting device for adjusting the grinding height is provided on the lateral rotation mechanism. A grinding and detection unit for grinding the rail surface is provided on the four-link lifting device.

[0007] The horizontal rotation mechanism includes a horizontal rotation base, which is fitted with the cloud platform rotation disk in the cloud platform rotation device and assembled together by bolt connection. A first rotation joint shaft is rotatably connected to the horizontal rotation base. A rotation connection block is installed on the outer wall of the first rotation joint shaft. A second rotation joint shaft is installed at the other end of the rotation connection block. A horizontal rotation support is rotatably connected to the second rotation joint shaft. By rotating the rotation connection block around the second rotation joint shaft for horizontal rotation, the horizontal grinding of the grinding head can be realized.

[0011] The grinding and detection unit includes a motor mounting bracket installed on the second connection support. A second motor is installed on the motor mounting bracket. Two groups of laser displacement sensors are installed on the second motor. The flatness of the rail surface can be detected by the laser displacement sensors to judge whether the rail surface needs to be ground and repaired. At the same time, after the grinding operation, the effect of the device grinding the rail surface can also be detected by the laser displacement sensors to see if it is flat and meets the requirements of the rail grinding specification. The output end of the second motor is connected with a grinding head, and the grinding head is driven to perform the grinding operation through a coupling.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0026] Embodiment 1

[0027] In the prior art, it is not easy to quickly grind and maintain each part of the steel rail. This embodiment provides a multi-degree-of-freedom angle-adjustable steel rail profile grinding trolley. Please refer to Figures 1 - 6 ., which can meet various actual grinding working conditions by adjusting the angle during actual grinding operations, improving the efficiency of steel rail maintenance. The multi-degree-of-freedom angle-adjustable steel rail profile grinding trolley includes a box body 2 slidably connected to the walking and track tightening device 1 and a storage battery 3 installed inside the box body 2. A cloud platform slewing device 4 for adjusting the grinding angle and a transverse rotation mechanism 5 are provided on the box body 2. A four-link lifting device 6 for adjusting the grinding height is provided on the transverse rotation mechanism 5. A grinding and detection unit 7 for grinding the surface of the steel rail is provided on the four-link lifting device 6. The position of grinding can be adjusted through the cloud platform slewing device 4 and the transverse rotation mechanism 5, thereby improving the grinding efficiency of the steel rail. The four-link lifting device 6 can grind positions at different heights, and the grinding and detection unit 7 can grind the steel rail more smoothly.

[0028] During the process of grinding the rail, in order to adjust the lateral position of grinding, the lateral rotation mechanism 5 includes a lateral rotation base 51. A first rotation joint shaft 52 is rotatably connected to the lateral rotation base 51. A rotation connection block 53 is installed on the outer wall of the first rotation joint shaft 52. The other end of the rotation connection block 53 is installed with a second rotation joint shaft 54. A lateral rotation support 55 is rotatably connected to the second rotation joint shaft 54. By the rotation connection block 53 making a lateral rotation around the second rotation joint shaft 54, the lateral grinding of the grinding head 73 can be realized. By adjusting the lateral rotation mechanism 5, the rail surface can be ground back and forth laterally. At the same time, in cooperation with the four-link lifting device 6, the grinding and detection unit 7 can be moved to the side of the track to facilitate the grinding head 73 to grind the side of the rail head.

[0029] Embodiment 2

[0030] On the basis of Embodiment 1, as Figures 1 - 6 shown, due to the problem that it is not easy to quickly grind and maintain each part of the rail in the existing technology, but during the grinding process, the situation of uneven grinding is likely to occur, thus reducing the grinding and maintenance efficiency of the rail. Therefore, the device is also provided with a structure for detecting the grinding levelness.

[0031] During the process of grinding the rail, in order to meet the grinding of different positions of the rail, the pan-tilt slewing device 4 includes a first motor 41 installed inside the box body 2. The output end of the first motor 41 is connected with a first cylindrical gear 42. A second cylindrical gear 43 meshing with the first cylindrical gear 42 is rotatably connected to the box body 2. A pan-tilt slewing wheel disc 44 connected to the lateral rotation base 51 is threadedly connected around the center of the second cylindrical gear 43. By the operation of the first motor 41 driving the first cylindrical gear 42 to rotate, under the connection of the second cylindrical gear 43, the pan-tilt slewing wheel disc 44 can be driven to rotate, so that the circumferential angle of the grinding and detection unit 7 can be adjusted to 0 degrees, thus meeting the grinding of different positions of the rail.

[0032] During the process of grinding the rail, in order to be able to grind different positions of the rail more stably, the traveling and rail clamping device 1 includes a vehicle frame 11 movably connected to the traveling and rail clamping device 1. A rail wheel 12 adapted to the top end of the traveling and rail clamping device 1 is rotatably connected to the vehicle frame 11. A top wheel mounting plate 13 is installed inside the vehicle frame 11. A rail clamping wheel 14 adapted to the side of the rail clamping wheel 14 is installed on the top wheel mounting plate 13. Under the limit support of the rail wheel 12 and the rail clamping wheel 14, the box body 2 moves more stably, facilitating the stable movement of the whole device on the rail.

[0033] During the process of grinding the rail, in order to grind positions at different heights, the four-link lifting device 6 includes a first connecting support 61 connected to the lateral rotating support 55. A first connecting rod 62 is rotatably connected to the first connecting support 61. The other end of the first connecting rod 62 is rotatably connected to a second connecting support 63. A second connecting rod 64 is rotatably connected between the first connecting support 61 and the second connecting support 63. The height of the second connecting support 63 can be adjusted through the handrail 8, so that the height of the grinding and detection unit 7 can be adjusted, facilitating the grinding of positions at different heights and improving the grinding efficiency of the rail.

[0034] During the process of grinding and maintaining the rail, in order to detect whether the ground rail surface is flat and improve the grinding quality of the rail, the grinding and detection unit 7 includes a motor mounting bracket 74 installed on the second connecting support 63. Two groups of symmetrically distributed handrails 8 are installed on the motor mounting bracket 74. The height of the grinding head 73 can be adjusted through the handrails 8. A second motor 71 is installed on the motor mounting bracket 74. Two groups of laser displacement sensors 72 are installed on the second motor 71. The output end of the second motor 71 is connected to the grinding head 73. Through the detection of the laser displacement sensors 72, it can be detected whether the grinding surface is flat and whether it meets the specification requirements for grinding the rail. Thus, the rail is ground by the grinding head 73 to improve the grinding effect of the rail.
